Recently, we worked with a customer on a commercial fishing vessel that needed a replacement shaft seal for a 110mm shaft. The catch? The vessel was still operating, measurements were limited, installation space was extremely tight, and there was no room for guesswork.

Rather than forcing a standard solution to fit, our team designed a custom PSS/AES Shaft Seal system that could be adapted on-site. We also specified SiC/SiC sealing faces to handle the vessel's harsh, silty operating environment and provide long-term reliability.

Projects like this are a great reminder that successful shaft seal installations aren't always about the product itself. They're about understanding the application, working through real-world challenges, and finding practical solutions that keep vessels working.

One of the most common questions we hear from boat owners, installers, and marine professionals is:

"What's the difference between a PSS Shaft Seal and a lip seal?"

Our newest ADVANCE course takes a practical, side-by-side look at both technologies, covering how they work, their strengths and limitations, and the impact each can have on shaft wear, maintenance requirements, installation flexibility, and long-term reliability.

Whether you're a boatyard technician, installer, dealer, surveyor, or vessel owner, this course provides valuable insight into selecting and maintaining the right shaft sealing solution for your application.

Should I get the PSS Type A or the Pro Shaft Seal? We get this question a lot. The truth is, you can't go wrong with either one.

Both the PSS Type A Shaft Seal and PSS Pro Shaft Seal use the same proven mechanical face seal design that's been keeping boat bilges dry for decades. The main difference comes down to the bellows material and maintenance interval.

The Type A Shaft Seal uses a nitrile rubber bellows and has a recommended service interval of 6 years. It's the seal that boat owners, boatbuilders, and marine professionals have trusted for years.

The PSS Pro Shaft Seal takes things a step further with reinforced silicone bellows, an extended 8-10 year maintenance interval, and a built-in Shaft Retention Collar (SRC) for added security.

For many boat owners, the Type A is the perfect fit. For those looking for longer service intervals and some additional peace of mind, the Pro Shaft Seal is worth the upgrade.

At the end of the day, both seals are built around the same goal: reliable, dripless performance so you can spend less time worrying about your shaft seal and more time enjoying your boat.

This short animation breaks shows exactly how the PSS Shaft Seal creates a watertight seal around the propeller shaft without the constant dripping associated with traditional packing glands.

Simple in design, yet proven in the real world, and trusted by boat owners, builders, and marine professionals around the world.

We're excited to welcome Owen Planck to PSS Seal as our new Logistics Apprentice!

Owen has already jumped right in and is learning the ropes. We're glad to have him on the team and look forward to watching him grow in his new role.

When he's not at work, Owen enjoys studying zoology, exploring film production, and spending time camping outdoors. His curiosity and eagerness to learn make him a great fit for our team.

Welcome aboard, Owen, we're excited to have you with us!

Recently, Aaron Stephenson visited longtime PSS Seal customer Javier Garcia and the team at Marine Supplies in Cancún, Mexico to connect on a recent project.

This project supports Ultramar Ferry, a leading passenger ferry operator in the region. Ultramar runs a modern fleet of high-speed ferries connecting Cancún, Isla Mujeres, Playa del Carmen, and Cozumel—playing an important role in daily transportation and tourism. Their vessels are designed for comfort, efficiency, and reliability, with capacities ranging from 150 to 800 passengers.

Visits like this go a long way. Spending time face to face helps us better understand how these vessels operate in the real world, share ideas, and continue delivering the support our customers count on.

A big thank you to Javier and the Ultramar team for the warm welcome and continued partnership. We truly appreciate the relationship and look forward to what’s ahead.

Two weeks to go until the Scottish Skipper Expo!

We’re excited to be heading to Aberdeen on May 7–8 for this biennial event that brings the commercial fishing industry together under one roof.

During the show, PSS Seal, alongside Neil Nutter of AESSEAL plc, will be available to discuss how the PSS Shaft Seal supports commercial vessels with a proven, low‑maintenance approach to shaft sealing, designed to perform in demanding real‑world conditions.

PJ Cloete and Dylan Beever of AVT Reliability will also be in attendance, showcasing the Machine Sentry platform and associated asset reliability management services and training.

Whether you’re exploring new equipment, planning refits, or looking to reduce ongoing maintenance issues, we’d welcome the chance to connect.

When a major theme park updated its fleet of passenger boats, reliability wasn’t optional. These vessels run all day, every day, with little room for downtime—and absolutely no tolerance for bilge water.

By switching to PSS Seal, the operator was able to move away from traditional packing systems and simplify life for their maintenance team. The results were exactly what they were looking for:
✔ Less routine maintenance and fewer last‑minute fixes
✔ Clean, dry bilges with true dripless operation
✔ Consistent performance, even under continuous daily use

This installation used a 35mm shaft with a 3” stern tube, and the PSS Type A’s non‑contact design and long service interval proved to be a great fit for a high‑use, highly visible application—where everything just has to work.

Working with AESSEAL, our team at PSS Seal recently partnered to design and manufacture a custom seal and fl**ge assembly for a challenging limited‑space application. With a 110mm shaft diameter and tight installation constraints, this project required close coordination between engineering, design, and manufacturing from start to finish.

By combining AESSEAL’s mechanical sealing expertise with PSS Seal’s application knowledge, we were able to develop a compact solution that met both dimensional and performance requirements, without compromising reliability.

A full case study, along with installation photos, will be shared soon. Stay tuned for a deeper look at how this solution came together.
